Voicemail system with quality assurance

ABSTRACT

In one embodiment, a method for ensuring quality of a media message is provided. The method includes receiving information for a media message. At least a portion of the media is analyzed to determine a media quality for the media message. The method then determines if the media quality is acceptable. If the media quality is not acceptable, then an alert may be sent regarding the media quality of the media message. For example, a caller may be prompted to re-record a media message.

TECHNICAL FIELD

Particular embodiments generally relate to telecommunications.

BACKGROUND

As callers leave media messages using a media system, most systemsmonitor the power of the recorded message. If the power of the messageis below a preconfigured threshold, the media system alerts the callerthat the recipient may have a hard time understanding the message. Forexample, the media system may play a suitable prompt, such as “We didnot receive your message. Please press 1 and re-record the message atthe sound of the beep.”

Power monitoring is used because old systems wanted to save disk spaceand because this simple measurement requires little CPU processingpower. Measuring the power may be acceptable for detecting silence;however, additional factors may affect the quality of a media messageother than power. Thus, even if power is monitored, a recipient maystill not be able to understand a media message.

DESCRIPTION OF EXAMPLE EMBODIMENTS Overview

In one embodiment, a method for ensuring voice quality of a mediamessage is provided. The method includes receiving information for amedia message. At least a portion of the information is analyzed todetermine voice quality for the media message. The method thendetermines if the voice quality is acceptable. If the voice quality isnot acceptable, then an alert may be sent regarding the voice quality ofthe media message. For example, a caller may be prompted to re-record amedia message.

Example Embodiments

FIG. 1 depicts an example system 100 for providing quality assurance fora voicemail system 102. A caller end point 104 may contact voicemailsystem 102. A caller may use caller end point 104 to record/leave amessage for a recipient. A recipient may use a recipient device 106 tolisten to a media message left using voicemail system 102.

Voicemail system 102 may be any system that allows media messages to berecorded. For example, voicemail system 102 may include a media isconnected to caller end point 104. A caller may then use caller endpoint 104 to record and store a media message with voicemail system 102.Although a “voicemail system” is discussed, it will be understood thatany system that can store media for quality analysis may be used, suchas a unified messaging system, instant messaging system, etc. The mediamessage may include any data in any form. For example, the media messagemay be a voice message, video message, any multimedia message, etc.

Caller end point 104 may be any device/application that can leave/recorda media message. For example, caller end point 104 may include acellular phone, PSTN phone, instant messaging client with voice enabled,laptop computer application, VoIP telephone, video phone, etc.

In one embodiment, caller end point 104 may attempt to contact arecipient. If the recipient does not answer the call, then voicemailsystem 102 picks up the call (e.g., the call is redirected to avoicemail server).

Voicemail system 102 includes an interactive voice response (IVR) systemthat may allow a caller to leave a media message for the recipient. Amenu system is provided that allows the caller to record/leave a mediamessage.

Particular embodiments analyze information for a media message beingleft to determine the media message's media quality. Media quality ismeasured in real-time as a caller leaves a message that is audible(i.e., has enough power) but the media quality may be poor. The mediaquality may be any analysis on the quality of the media message. Forexample, the recording quality of the media message is analyzed. Thismay analyze the voice quality of the media message. Further, the mediaquality may analyze other aspects of the media quality, such as whetherthe video can be understood (either voice or video quality). If amessage is considered to have poor media quality, the message may behard to understand for various reasons. For example, when a caller isusing a cellular phone, there may be a poor connection when leaving themessage. Thus, the caller's voice may be muffled, garbled, roboticsounding, etc. When a recipient listens to a media message with poormedia quality, the recipient may not be able to understand or comprehendwhat the caller has sent e.g., what the caller has spoken, sent in avideo, etc.). This is different than when the power is low in thateither nothing was said or the recipient cannot hear audio in the mediamessage that was left.

When the voicemail system 102 determines that the media quality isunacceptable for a media message, then it may send an alert indicatingthat the media quality is not acceptable. For example, voicemail system102 may send a prompt to a caller indicating that the media quality isnot acceptable and suggest that the caller may want to re-record a newmessage. Accordingly, the caller may record another message in place ofthe already left message.

FIG. 2 shows an example of a method 200 for determining media quality.Step 202 receives media for a media message. The media received for themedia message may be media from the actual media message being left bythe caller. For example, packets of media may be received with audioinformation for the media message. Also, the information may be dataother than the actual media message spoken by the caller. For example,the information may be numbers of packets lost, transmission channelerrors, a noise reading, transcoding information, delay in packets beingsent, short-term and long-term warping of a speech signal, a frequencysignature of the media, a speech recognition of the audio of the mediamessage, etc.

Step 204 then analyzes the information media quality. Various methodsmay be used to analyze the media quality. For example, voice qualityalgorithms that measure the quality of voice may be used. In oneembodiment, algorithms described in the standards ITU P.VTQ or P.563 foranalyzing voice quality (VQ) may be used. An example of the P.563standard is described in ITU P.563 recommendation “Single-ended Methodfor Objective Speech Quality Assessment in Narrow-band Telephonyapplications”, which is incorporated by reference in their entirety forall purposes.

In one embodiment, the algorithms may accurately detect the following:impairments of packet loss and packet loss concealment with code-excitedlinear prediction (CELP) codecs, transmission channel errors,environmental noise at the sending side, transcodings, effect of varyingdelay on listening quality in absolute category rating (ACR) tests,short-term time warping of a speech signal, long-term time warping of aspeech signal, etc. Other impairments may also be detected. For example,a robotic voice signature that may be caused by packet loss concealmentmay also be detected.

Other analysis may also be used. For example, natural languagerecognition (NLR) may be used to parse the recorded media message. Ifvoicemail system 102 has difficulty deciphering parts of the message,then it may be determined that the media quality is poor.

In another embodiment, voicemail system 102 may identify segments in themedia message that contain poor media quality by estimating poorcellular connectivity. For example, certain signature or frequencies ofa spectrum filter suggest that voice may be distorted.

Further, packet loss concealment may be used. In VoIP, packets may belost along the way to voicemail system 102. If enough packets are lost,then it may be assumed that there is poor media quality.

In another specific embodiment, step 204 may utilize video qualityanalyzing algorithms. Various methods may be used to analyze the videoquality. For example, video quality algorithms that measure the qualityof video may be used. In one embodiment, algorithms described in thestandards ITU STUDY GROUP 9 of the Video Quality Experts Group (VQEG)for analyzing video quality (VQ) may be used. The “final Report from theVideo Quality Experts Group on the Validation of Objective Models ofVideo Quality Assessment” is incorporated by reference in their entiretyfor all purposes. This report describes the results of the evaluationprocess of objective video quality models as submitted to the VideoQuality Experts Group (VQEG). The report describes models to be used inthe calculation of objective scores for comparison with subjectiveevaluation over a broad range of video systems and source sequences.

Step 206 then determines if the media quality is acceptable. Forexample, the analysis in step 204 may provide a measurement data point.This data point may be compared to a threshold to determine whether themedia quality is acceptable or not. For example, if a number of packetsare lost above a certain threshold, it may be determined that the mediaquality is poor. Also, any of the impairments discussed above may becompared to a threshold to determine if media quality is poor or not.Further, in speech recognition, if a large number of words are notrecognized above a threshold, then it may be determined that therecipient may have trouble understanding the media message and thus itmay be considered of poor media quality.

In one embodiment, segments of a media message may be analyzed for mediaquality. Instead of analyzing the entire message as a whole, shortsegments may be analyzed for media quality rather than analyzing theaverage overall quality of a media message. For example, voicemailsystem 102 may treat the overall media message as a sequence of a numberof segments and may measure the media quality of each segment. Ifvoicemail system 102 determines that any of the segments include poormedia quality, then these segments may be flagged as being of poor mediaquality. However, segments that are of acceptable media quality may notbe flagged.

If the media message is considered acceptable, step 208 accepts themedia message. For example, the whole media message or none of thesegments of the media message may have been considered to be poor.

If the media message is not considered acceptable, then step 210performs an action in response to the poor quality determination, suchas sending an alert indicating that it was determined that the mediamessage was not considered acceptable. If the entire message isconsidered poor (or the determination was averaged for the entire mediamessage), then the caller may be asked to re-record the media messageagain. Also, different way of treating segments of poor quality may beused. For example, the caller may be asked to re-record the segmentsthat were considered of a poor quality. Also, the caller may be able tore-record the entire message from the beginning even though only a fewsegments were considered unacceptable.

Another option may be that the caller can listen to the segments or theentire media message and determine if the media quality is acceptable.If the media quality is acceptable, the caller may commit it tovoicemail system 102. If the media quality is not acceptable, then thecaller may re-record a new message.

A selective analysis of media quality may also be performed. Forexample, voicemail system 102 may detect when a media message is beingleft from a medium that may result in poor media quality. In oneexample, voicemail system 102 may detect that a caller is leaving amessage from a mobile phone. This may be performed by using the callerID of incoming calls to determine if the call originates from a mobilephone. Thus, users in media in which it is not likely that poor mediaquality results may not have to deal with false positives indicatingthat media quality is poor. For example, callers using PSTN telephonesmay not need to have their media quality analyzed. Also, carriers mayprovide analysis on certain calls, such as a phone company may providequality assurance on calls between two end points it owns. This mayprovide better voice quality for customers using the same phone company.However, if the call is from an end point from another carrier, thequality assurance may not be provided.

FIG. 3 depicts a more detailed example of voicemail system 102. Asshown, a media quality analyzer 302 and a media quality alerter 304 areprovided. Media quality analyzer 302 is configured to receiveinformation for the media message. Media quality analyzer 302 thenanalyzes the information for media quality. It can then determine if themedia quality is acceptable or not.

If the media quality is not acceptable, then media quality alerter 304is configured to alert a caller of the poor media quality. Media qualityalerter 304 may then give the caller options of checking the media formedia quality, re-recording the message, etc.

Accordingly, particular embodiments provide many advantages. When acaller leaves a media message and hangs up, the caller cannot go backand change the message that has been left in the recipient's voicemailbox. Thus, it is important to ensure that the media quality of the mediamessage being left is acceptable while the caller is connected tovoicemail system 102. Thus, real time media quality assurance isprovided using particular embodiments. If it is detected that mediaquality is poor, then the caller may be alerted before disconnectingfrom voicemail system 102. This may allow a caller to re-record a mediamessage if the media quality is poor. This ensures that media messagesleft are of good voice quality.

Checking the quality of a recorded message is useful as new media arebeing used to make calls, such as VoIP, cellular, video phones, landmobile radios (LMR), etc. These new media may not be as reliable asother technologies. Further, the intercommunication between end pointsin different mediums may not always produce the highest quality voicecalls. Thus, ensuring that voice quality is acceptable may be moreimportant than detecting silence (e.g. the power).

Also, particular embodiments may be useful when quality assurance isimperative in media recordings. For example, some fields requirerecording and storing of all media messages for regulatory or legalreasons. Also, for legal reasons, some companies may need to keep mediamessages. If the stored messages have poor voice quality, theirusefulness may be degraded. Thus, techniques to ensure good recordingquality are desirable.
